Can anyone help? I noticed my air vent tube was missing when i had to carry my bike up stairs and it started to pour fuel out everywere. This happen when i lifted the front wheel to about 10:30. Tank came off and there was no tube attached. Wherewouldthat tube go ifit was on thereand why was it pouring out fuel when the front was up? Why was fuel comming out it at all, does it do that when i wheelie?[:-]

Was it your air vent or the overflow tube? I believe the air vent is smaller around than the overflow. Both should be a hose that hangs down to let fuel hit the ground, the overflow is sealed off when the cap is closed, so maybe your cap doesn't seal well. Otherwise the air vent also goes up to the cap, but not on the sealed side. It is soldered into the ring under the cap assembly and is designed to keep fuel from splashing into it but also keep any kind of vapor pressure from building up. I would guess even with the wheel that high you'd need more than 3/4 of a tank of fuel to get any kind of major spill from it.

 

Yeah it had a completely full tank. The cap leaked abit when i turned the tank upside down to put it down. As i had to get the tank off in a hurry i left the over flow tube attached to the tank, do you know exactly were it hangs down as well as the air vent tube? for when i put it back on..

 

It should go between the swing arm and swing arm bracket according to the manual. I let mine hang next to the gear change in front of the sprocket cover. So long as it won't drain onto the hot exhaust piping It doesn't matter much.
